THE DARWINIAN THEORY 



" It is now half a century since Darwin's 

 work on the Origin of Species by Natural 

 Descent has been published. Up to the 

 present day it is an undisputable fact that 

 not a single variety or species of any wild 

 animal or plant has ever been proved to 

 have had its origin by means of natural 

 selection." 



The eminent Russian botanist, H. Kor- 

 chinsky, labors to prove that natural se- 

 lection, to use an American phrase, does 

 not select worth a cent, but if anything 

 prevents the formation of new species. 

 His five propositions, which we have nc 

 room to quote, by which he claims to show 

 that natural selection has no real power to 

 select, contrast greatly with the expres- 

 sions of some writers who imagine that 

 natural selection has been operating 

 through infinite time in the past. But as 

 the remains of multicellular living forms 

 occur first only in the lower Cambrian
